Question

I’m sure I’m missing something very simple on this one. After banging my head against the desk (literally) for a couple of days now, I submit myself to the mercy of the stack:

I’m using jQuery UI Autocomplete as a combobox in my jQGrid (I know! I’ve already looked for the solution elsewhere to no avail!). I would like the dropdown to open when I access the cell for editing through the onSelectRow event in jqGrid. Basically, I want to do exactly what is discussed here:

Open jQuery UI ComboBox on focus

and demo’d here:

http://jsfiddle.net/gEuTV/

The only difference is that I need it in jqGrid. I’ve tried the code below which I (mistakenly) through would trigger the combobox to appear when the row is focused, but the combobox doesn’t appear on focus of the row in the onSelect event. I have a sneaking suspicion that I’m just putting the following code in the wrong spot, but I’ve tried it everywhere I can think of:

$("#"+id+"_usr_validation","#list2").bind("focus", function () {
this.value = '';
$(this).autocomplete("search", ''); 

Here’s my complete code including the grid:

$(function(){
    var lastsel;
     $("#list2").jqGrid({
            url: 'php_includes/uploadgrid.php',
            datatype: "json",
            mtype: 'GET',
            colNames:[
                    'User Value',
                    'Translated Value',
                    'User Validation,
                    ],
            colModel:[
                    {name:'usr_value',index:'usr_value', sortable:'true', width:60, align:"center", editable:false},
                    {name:'translated_value',index:'translated_value', sortable:'true', width:60, align:"center", editable:false},
                    {name:'usr_validation',index:'usr_validation', sortable:'true', width:60, align:"center", editable:true}
                    ],
            pager: '#pager2',
            rowNum: 1000,
            scroll: true,
            gridview: true,

            autowidth: true,
            pgbuttons: false,
            pginput: false,
            forceFit: true,
            emptyrecords: "No record was loaded",
            onSelectRow: function(id){
                            if(id && id==lastsel){
                                    $("#list2").jqGrid('editRow',id,true,autocomp,'','','',selectNone);
                                    } else {
                            if(id && id!==lastsel){
                                    $("#list2").jqGrid('saveRow',lastsel);
                                    $("#list2").jqGrid('editRow',id,true,autocomp,'','','',selectNone);
                                    lastsel=id;
                                    }
                                }
                            },
            editurl: '/php_includes/jqGridCrud.php',
            });
            jQuery("#list2").jqGrid('navGrid',"#pager2",{edit:false, search:false, del:false, add:false})

         function selectNone(){
                     $("#list2").jqGrid('resetSelection');
                    }
                    //this function de-selects all previously accessed rows

            function autocomp(id) {
                    var term2 = $("#list2").jqGrid('getCell',id,'usr_value');
                    $("#"+id+"_usr_validation","#list2")
                            .autocomplete({
                                    source: function(request, response) {
                                              $.ajax({

Answer 1

You should change 'User Validation, to 'User Validation' and remove trailing commas in different places of your code (like from editurl: '/php_includes/jqGridCrud.php',} and close which are syntax errors in JavaScript, but ignored in many, but not all web browsers).

UPDATED: One more problem is that the focus on the editing field will be set before oneditfunc will be called, so the “focus” event can not be triggered. As a workaround you can trigger “focus” event directly after the .bind("focus", ....

See your modified demo here.
